Never heard of that one to be honest

Try using the 1.8MAF with the 1.6 MAF sensor or the otherway around as am not convinced its working right - Or alternativly disconnect it and see how it acts

im using the 1.8 housing with 1.6 sensorbox in dude,
the above way is apparently the correct way to start it,when the key is turned the ECU communicates with the chip near the lock,which shud be the one matched to the ECU,if 2 signals are found then it wont understand whats goin on,i suppose,in principal,it works the same way as IFF on the jets,bit of RAF talk there for ya

The chip in the key only removes the PAT to be able to start the car, I thought ?

Try disconnecting the MAF, if it makes an improvement then the MAF is faulty and if not then its something else.

Nothing silly like the exhaust is blowing is there?

zorst is fine,the engine runs and sounds sweet,its only when ur on full throttle the engine just doesnt want to rev up smoothly,it goes quickly up a few hundred RPM,then slows its rate down a tad,then speeds up,then slows down

The chip is what disables the immob and alarm,the key will happily turn (as its the right shape) but the chip is what tells the PATS system that its the correct key,IE/if u double lock the car,then open it WITHOUT using the correct keychipped key,then the alarm goes off as u open it,and the engine wont start unless the correct code is recieved from the key when its turned to III

We'll see what happens next week when i try it,but i damaged the chip removing it from my mates 1.8 carkeys,only the protective cover of it tho

Ill try unpluggin the MAF when i drive to work tomorrow mate,but i doubt its that,it may just be the ECU bein unable to calculate the fuel for the air im running

After 3 months of running 1.8 im finally about to fit a 1.8 ECU and have all sensors running. So i shud finally see over 110BHP. Woohoo. Gettin a new ECU from ebay,im winning the bid

turbo it haha

had a 130 spec ecu and cams the other month shame i wasn't on cruise wirral that time or i would of sold them ya.

a little hint tho look out for orion si ghia's as they have 130spec engines in.

will keep eyes out for a 130spec ecu if ya want?

its alright now,sorted it. Bought a mondeo 115 ECU and adapted the loom to fit, works a charm,i now have the full 115+PS under my right foot and the increase ive noticed between 4 and 6k is huge. Pulls like a train now (compared to what it used to do) Idles really clean aswell

OK,the above quote was wrong. It WAS running rich when i initially fitted the BLOB ecu,now ive wired the air inlet temp sensor in and changed the plugs and now i believe its running full power. Not as fast over 4k but it WAS fast over 4k due the mixture being good up top end where the cams are "on song" Now its got good power delivery with the flat spot inherent to zetecs evident.GEtting it emissions checked next week to ensure its running stoich

Time to start modding then. First up is peco backbox and standard centre box removal (purely for noise)

Below comment aimed at CLJ and dazza


a mondeo does need to carry more load than the escort but the engine produces the exact same power/torque so the map is the same (give or take). The car wont be as quick as its a heavier car with the same engine. Are u seriously trying to suggest that they would have given the mondie 1.8 more grunt??

Its the same engine and same running of that engine. The map may have changed each year to get the engine to run a tiny bit more efficiently without sacrificing power but the engine components remain the same.So the ZETEC-E 1.8 will run on any ECU aslong as the PATS is matched or bypassed.

Last sentence is correct.

Yes the power is the same since they are using the same engine etc, the difference in maps is about load. X amount of load will alter the fuel ratio among other things. You will not notice this but am just making it known that its there.

Think of it this way, if these maps weren't there then if you have 5 passengers plus luggage going up a hill the engine will struggle to produce the torque needed so adjustments are made to cater for this. Using the same scenareo, if only the driver is there then another map would be used so not to give too rich a mixture etc - There are hundreads of maps each doing its own little bit to cater for a certain scenareo.
